It was

An object of the present invention is to provide a locking device for a gaming machine that cannot be unlocked when the store is closed.

[0007]

[Means for Solving the Problems]

 As a means for solving the above problems, the configuration described in claim 1 can be adopted. This locking device supplies power to the front frame lock member that is displaced to a release position that allows displacement of the front frame locking member to the unlocked position and a lock position that does not allow displacement of the front frame locking member to the unlocked position. In the ON state, the front frame lock member is displaced to the release position, and when the power is cut off, the drive mechanism is provided to displace the front frame lock member to the lock position. If turned off, the power of the gaming machine is also turned off and the locking device is turned off, so the unlocking operation cannot be performed manually even with the key. Therefore, it is possible to prevent fraudulent acts such as opening the front frame and closing the game control base when the store is closed.

Further, as described in claim 2, a glass frame releasing position that allows the glass frame locking member to be displaced to the glass frame unlocking position and a glass that does not allow the glass frame locking member to be displaced to the glass frame unlocking position. A configuration is provided in which a glass frame lock member that displaces to the frame lock position is provided, and the drive mechanism displaces the glass frame lock member to the glass frame release position in the on state, and displaces the glass frame lock member to the glass frame lock position in the off state. You can also With this configuration, the glass frame cannot be unlocked by turning off the power of the game machine, and thus it is possible to prevent illegal acts such as bending the obstacle nail on the game board surface.

According to a third aspect of the present invention, a key detecting means for outputting a key detecting signal when detecting that the key is attached to the key receiving portion, and a switching means for turning on the driving mechanism when there is the key detecting signal. If the key is installed, electric power is supplied to the drive unit just by mounting the key, so no special operation is required when opening the front frame or the glass frame. Therefore, the unlocking operation can be performed as before.

If the output terminal for outputting the key detection signal to the outside is provided as in claim 4, the hall computer can be used to open the front frame or the glass frame during business by using the key detection signal. It can be used for hall management and crime prevention, such as recording it in etc. and making a notification by voice or visible light.

[Embodiment of device]

 Next, in order to further clarify the embodiment of the present invention, an example of a locking device for a gaming machine to which the present invention is applied will be described with reference to the drawings. The embodiments described below are merely one embodiment of the present invention, and the embodiments of the present invention are not limited to the specific shapes and the like illustrated below.

[0013]

【Example】

 As shown in FIG. 1, the pachinko machine 11 includes a box-shaped outer frame 12. The outer frame 12 is a member that supports each part of the pachinko machine 11 and is also installed on an unillustrated gaming machine installation island (hereinafter, also simply referred to as an island). A pair of hinges 13 are provided above and below the front left of the outer frame 12, and the front frame 14 is attached to the outer frame 12 so as to be openable and closable with the hinges 13 serving as spindles.

On the inner surface on the right side of the outer frame 12, two engaging fittings 15 for locking the front frame 14 in cooperation with a slide lock 38 described later are provided. The front frame 14 has a window 16 and a metal frame 17 is attached around the window 16. A glass frame 36 is openably and closably attached to the metal frame 17 via a support shaft (not shown). Further, a glass frame locking device 37 is attached to the right side 18 of the metal frame 17.

A cylinder lock 41, the details of which will be described later, is attached to the front frame right side 19 of the front frame 14 with the keyhole surface 20 exposed on the front surface, and the back surface of the front frame right side 19 will be described in detail later. A slide lock 38 is installed. A pair of metal frame latch plates 56 are attached to the right side surface of the glass frame 36.

As shown in FIG. 2, FIG. 3, FIG. 4, and FIG. 5, the mounting portion 22 of the angle-shaped base metal plate 23, which is composed of the upright portion 21 and the mounting portion 22, is attached to the back surface of the right side 19 of the front frame by screws. It is fixed. A pair of hooks 24 are rotatably attached to the upper and lower ends of the upright portion 21 via tilting shaft pins 31. The hook 24 has a shape in which a hook tip 25 having a right triangle shape and a rectangular arm 26 are joined to each other, and a step 27 is formed between the hook tip 25 and the arm 26.

A connecting shaft pin 32 penetrating the rear end of the arm portion 26 has its head loosely fitted in an elongated hole 28 provided in the upright portion 21 of the base sheet metal 23, and the hook 24 is connected to the connecting shaft pin 32. The hook tip portion 25 can be swung within the free range of the pin 32. A front frame slide 30 is connected to the hook 24 via a connecting shaft pin 32.

The front frame slide 30 is laid along the upright portion 21 of the base metal plate 23 and can reciprocate within the free range of the connecting shaft pin 32. The front frame slide 30 is provided with a slide bar 39 and an A knob 33 that project in parallel with the mounting portion 22 of the base sheet metal 23.

Further, the base sheet metal 23 is provided with a B knob 34 below the mounting portion 22. A tension spring 35 is hooked between the B knob 34 and the A knob 33, and the front frame slide 30 is biased in the direction of arrow D by the tension spring 35. A glass frame slide 40 is laid between the upright portion 21 and the front frame slide 30, and a glass frame opening plate 48 that projects over the upright portion 21 is provided at the center of the glass frame slide 40. ing.

The glass frame slide 40 is held by the upright portion 21 by penetrating a slide pin 47 fixed to the upright portion 21. However, since the slide pin 47 penetrates an elongated hole (not shown) provided in the glass frame slide 40, the glass frame slide 40 can reciprocate in the directions of arrows U and D.

The slide pin 47 also penetrates an elongated hole (not shown) of the front frame slide 30. Therefore, the front frame slide 30 is held by the upright portion 21, but the reciprocating movement in the arrow U and D directions is not hindered. The glass frame slide 40 is provided with a C knob 52 that projects in parallel with the mounting portion 22 of the base metal plate 23. The C-knob 52 does not interfere with the reciprocating movement of the front frame slide 30 because it protrudes through the elongated hole (not shown) of the front frame slide 30.

On the other hand, a D knob 53 is provided above the mounting portion 22 of the base sheet metal 23, and a tension spring 58 is provided between the D knob 53 and the C knob 52. Therefore, the glass frame slide 40 is biased in the direction of arrow D by the tension spring 58.

The lock shaft 63 of the cylinder lock 41 rotatably penetrates the mounting portion 22, and a vertical cam 64 and a flat cam 65 are provided at the tip thereof. The lock shaft 63 can be rotated clockwise and counterclockwise (directions of arrows L and R in FIG. 1) via the key 57, and the standing cam 64 and the flat cam 65 can be rotationally displaced accordingly. .

When the lock shaft 63 is rotated counterclockwise by the key 57, the standing cam 64 pushes up the slide bar 39 and moves the front frame slide 30 in the arrow U direction. As a result, the front frame slide 30 tilts the hook 24 and the step 27 of the hook 24 is disengaged from the engagement fitting 15, so that the front frame 14 can be opened.

When locking the front frame 14, when the front frame 14 is pushed, the inclined portion 29 of the hook tip portion 25 comes into contact with the engaging fitting 15 and the hook 24 is pushed down. Further, when the front frame 14 is moved forward, the inclined portion 29 passes under the engagement fitting 15, and the step 27 and the engagement fitting 15 engage with each other. As a result, the front frame 14 is locked.

Further, when the lock shaft 63 is rotated clockwise, the flat cam 65 pushes down the glass frame slide 40 in the arrow D direction. At this time, the glass frame opening plate 48 also moves and the metal frame lever 59 is pushed down. The metal frame lever 59 is a part of the glass frame locking device 37.

Next, the glass frame locking device 37 will be described. The glass frame locking device 37 is attached to the right side 18 of the metal frame by a base plate metal 51. A slide flat plate 45 having a pair of guide grooves 54 is superposed on the base metal plate 51. A pair of slide pins 47 are fixed to the base metal plate 51.

The slide pin 47 penetrates the guide groove 54 of the slide flat plate 45. Therefore, the slide flat plate 45 can reciprocate in the directions of the arrows U and D within the range of the guide groove 54. The above-mentioned metal frame lever 59 is fixed to the slide flat plate 45, and acute-angled glass frame engaging portions 49a and 49b are provided. The metal frame latch plate 56 can be engaged with and disengaged from the glass frame engaging portions 49a and 49b when the glass frame 36 is closed.

The base metal plate 51 has an E-knob 60 at its tip, and a tension spring 62 is hooked between the E-knob 60 and the F-knob 61 provided on the slide flat plate 45. Therefore, the slide flat plate 45 is biased in the direction of arrow U in FIGS. A slide latch 50 is swingably attached to the slide plate 45 with a latch shaft pin 68 as a support shaft. The slide latch 50 has a substantially isosceles triangular shape, and a latch shaft pin 68 penetrates the apex thereof. A glass frame pusher 67 is attached to one corner on the bottom side of the slide latch 50, and a latch pin 66 is fixed to the other corner.

The push spring 43 is loosely fitted to the latch shaft pin 68. One end of the push spring 43 is hooked on the glass frame push 67, and the other end is hooked on the spring pin 42 which is erected on the slide flat plate 45. As a result, the slide latch 50 is biased toward the glass frame 36 side by the pressing spring 43.

A mooring groove 46 is provided at the center of the right side 18 of the metal frame. When the metal frame lever 59 is pushed down in the arrow D direction by the movement of the glass frame opening plate 48 in the arrow D direction, the slide flat plate 45 also moves in the arrow D direction. When the slide flat plate 45 moves, the metal frame latch plate 56 is disengaged from the glass frame engaging portions 49a and 49b.

When the slide flat plate 45 moves in the direction of arrow D, the latch pin 66 enters the mooring groove 46. Then, the slide latch 50 pops out toward the glass frame 36, and the glass frame pusher 67 pushes out the glass frame 36 to open the glass frame 36. At this time, since the latch pin 66 of the metal frame lever 59 is locked in the mooring groove 46, the metal frame lever 59 remains stopped downward.

When locking the glass frame 36, if the glass frame 36 is pushed toward the front frame 14, the glass frame 36 pushes the glass frame push 67, so that the latch pin 66 is disengaged from the mooring groove 46. When the latch pin 66 is released, the slide flat plate 45 moves in the arrow U direction. Accordingly, the glass frame engaging portions 49a and 49b are engaged with the metal frame latch plate 56 so that the glass frame 36 can be locked.

The mechanism of the slide lock 38 has been described above, but the slide lock 38 itself is the same as the conventional one. Next, the lock device 70, which is the main part of the present invention, will be described with reference to FIGS.

The lock device 70 is installed inside the outer frame 12 at a position overlapping the slide lock 38. The lock device 70 includes a fixed base 71, and the fixed base 71 includes a base front end portion 72 and a base rear end portion 73. The base tip portion 72 is screwed to the outer frame 12 by a beam stopper 78 having a shaft stopper 76 and a beam stopper rib 77.

A frame fixing sheet metal 81 is fixed to a lower end portion of the fixed base 71, and the frame fixing sheet metal 81 is screwed to the bottom surface of the outer frame 12 via a frame fixing rib 80. A shaft 75 rotatably passes through the base end portion 72 and the base rear end portion 73 while vertically moving.

A substantially rectangular actuation plate 82 is attached to the shaft 75, and the actuation plate 82 is provided with attachment guides 83 a and 83 b. A shaft spring 84 is wound around the shaft 75. One end of the shaft spring 84 is inserted through the shaft 75, and the other end of the shaft spring 84 is bent and fixed to the fixed base 71. The shaft spring 84 is twisted and compressed vertically. Therefore, the shaft 75 is rotationally biased in the arrow R direction and pushed up in the arrow U direction.

A hook trap 85 having a substantially trapezoidal shape is screwed to the attachment guide 83b of the operation plate 82 so that the attachment position can be adjusted, and a lever stopper having a substantially trapezoidal inclined portion 74 is provided on the other attachment guide 83a. 86 is screwed so that the mounting position can be adjusted. The hook stop 85 is located below the hook 24 when the front frame 14 is closed, and hits the hook stop 85 when the hook 24 tries to tilt.

The lever stopper 86 is located below the metal frame lever 59 when the glass frame 36 is closed, and hits the lever stopper 86 when the lever stopper 86 tries to move in the direction of arrow D. The frame fixing sheet metal 81 is provided with an extending portion 91 formed in a substantially L shape, and a flapper solenoid 87 is attached to the extending portion 91.

The flapper solenoid 87 is well known, and when the flapper solenoid 87 is not energized, the tip of the electromagnetic plate 88 blocks the movement of the operating plate 82 in the direction of arrow D. When the flapper solenoid 87 is energized, the electromagnetic plate 88 swings and displaces, the operating plate 82 can move in the direction of arrow D, and the shaft 75 can also move.

A touch circuit 89 for supplying electric power to the flapper solenoid 87 is attached to the frame fixing sheet metal 81. Next, the touch circuit 89 will be described in detail with reference to FIG. The touch circuit 89 itself is a known one as described in, for example, JP-A-5-245253.

One end of the transmission code 90 is connected to the input section 92 of the touch circuit 89, and the other end of the transmission code 90 is connected to the mounting section 22. The touch circuit 89 includes a set / reset flip-flop 94 (hereinafter referred to as an RSFF circuit). The RSFF circuit 94 has input terminals S and R and output terminals Q and Q. The input terminals S and R are connected to the input section 92 via a resistor, and the input terminal R is connected to an oscillator circuit 95.

A filter circuit 96 is connected to the output terminals Q, Q , and a smoothing / power amplifier circuit 98 (hereinafter referred to as a power circuit) is connected to the output side of the filter circuit 96. The output section 93 of the power circuit 98 is connected to the flapper solenoid 87 via a harness wire 97.

When there is no input from the input unit 92, only the rectangular wave output from the oscillation circuit 95 is input to the input end R, so that the output ends Q and Q become alternating uniform rectangular waves (FIG. 7 (B)). RSFF circuits a and b). The rectangular waves at the output terminals Q, Q are shaped by the filter circuit 96 and formed into a whisker-like waveform in relation to the transmission speed (see the filter circuit VO in FIG. 7B). When this whisker-shaped waveform is smoothed by the power circuit 98, the level becomes 0 (see the output in FIG. 7B). Therefore, there is no power output from the power circuit 98, and the flapper solenoid 87 does not operate (output in FIG. 7B). reference).

When the noise from the input section 92 is input to the input end S, the waveform of the output end Q is compressed by the noise and distorted (see FIG. 7B'a '), but the waveform of the output end Q. Is normal because the input is held by the rectangular wave of the oscillation circuit 95 (see b ′ in FIG. 7B). If the distorted waveform and the normal waveform are shaped by the filter circuit 96, a rectangular wave having a width narrower by the rising delay is generated (see VO ′ in FIG. 7B). The flapper solenoid 87 can be operated by smoothing the rectangular wave by the power circuit 98, amplifying the power, and outputting the amplified power (see FIG. 7 (B) output ').

Next, the movement of the lock device 70 will be described. In the lock device 70, if the key 57 is inserted into the keyhole 55 while the island power supply is turned on, noise generated by the antenna action of the human body is transmitted to the touch circuit 89. Then, as described above, the electric power from the touch circuit 89 is supplied to the flapper solenoid 87, and the electromagnetic plate 88 is adsorbed, so that the operating plate 82 can move in the direction of arrow D in FIG.

Therefore, when the hook 24 tilts, the actuating plate 82 is pushed down (in the direction of arrow D in FIG. 6) together with the hook stop 85, so that the hook stop 85 does not prevent the hook 24 from tilting. Similarly, even when the glass frame 36 is opened, the metal frame lever 59 pushes the operating plate 82 downward (in the direction of arrow D in FIG. 6) together with the lever stop 86, so the lever stop 86 prevents the movement of the metal frame lever 59. There is no.

As a result, when the lock shaft 63 is rotated in the R direction in FIG. 1 by the key 57, the hook 24 tilts and disengages from the engagement fitting 15, so that the front frame 14 can be opened. Further, when the lock shaft 63 is rotated in the L direction of FIG. 1 by the key 57, the glass frame opening plate 48 moves the metal frame lever 59 in the direction of arrow D of FIG. 5, so that the glass frame engaging portions 49a and 49b are connected to the metal frame. The glass frame 36 can be released from the latch plate 56.

On the other hand, when the island power supply is not turned on, the touch circuit 89 is also in the off state, and the electromagnetic plate 88 of the flapper solenoid 87 is not attracted. Therefore, as shown in FIG. 6B, the operating plate 82 and the shaft 75 cannot move in the direction of arrow D in FIG. Therefore, the hook stop 85 prevents the hook 24 from tilting, and the lever stop 86 prevents the metal frame lever 59 from moving in the direction of arrow D in FIGS. Also, the glass frame 36 cannot be opened.

Next, when locking the front frame 14, if the front frame 14 is pushed toward the outer frame 12 regardless of whether the power is turned on or off in the game machine installation island, the tip of the hook 24 hits the hook stop 85 and is still in front. When the frame 14 is advanced, the tip of the hook 24 pushes the hook stopper 85. Then, the shaft 75 and the operating plate 82 rotate as shown in FIG. 8C, so that the hook 24 can move forward. The hook 24 engages with the engagement fitting 15 as described above. When the hook 24 engages with the engaging fitting 15, the hook 24 is disengaged from the hook stopper 85, so that the shaft 75 and the operating plate 82 return to their original positions.

Further, when the glass frame 36 is opened, the metal frame lever 59 is locked to the mooring groove 46 by the latch pin 66, so that the shaft 75 and the operating plate 82 below the metal frame lever 59 are separated from each other. It is pushed down and remains stopped. At this time, if the glass frame 36 is pushed toward the front frame 14, the glass frame 36 pushes the glass frame push 67, so that the latch pin 66 is disengaged from the mooring groove 46. Then, the metal frame lever 59 moves in the direction of arrow U in FIG. 5, the glass frame engaging portions 49a and 49b engage with the metal frame latch plate 56, and the glass frame 36 can be locked. Along with this, the shaft 75 and the operating plate 82, which were held by the metal frame lever 59, return to their original positions.

Therefore, the glass frame 36 can be locked regardless of whether or not the game machine installation island is powered on. By the way, when the glass frame 36 is opened, the shaft 75 and the operating plate 82 are rotated in the direction of arrow R in FIG. 6 for some reason, as shown in FIGS. 8B and 8C. There is a possibility that the stopper 86 may rise in the direction of the arrow U in FIG. However, if the glass frame 36 is pushed to lock the glass frame 36, the metal frame lever 59 pushes the inclined portion 69 to rotate the shaft 75 and the operating plate 82 to return to the position before the rotation. As a result, the metal frame lever 59 can move without being obstructed by the operating plate 82.

Therefore, even if the shaft 75 and the operating plate 82 move due to, for example, the glass frame 36 being randomly opened and closed, the locking can be performed without any problem. Even in a gaming machine that does not use the slide lock 38, the device of claim 1 can be used as long as it has a device for locking the front frame by engaging a locking metal fitting provided on the outer frame with a hook provided on the front frame. .

On the contrary, the same can be applied to a gaming machine in which a hook is provided on the outer frame and a locking metal fitting is provided on the front frame. By using the power output from the output unit 93 to light a lamp or activate a buzzer, it is possible to notify the employee or manager that the front frame 14 or the glass frame 36 has been opened. Also, if the signal from the output unit 93 is connected to a computer that manages the gaming state, the frequency of opening the front frame 14 and the glass frame 36 of each gaming machine is recorded, and there is a failure or a ball jam depending on the frequency. You can use it effectively in business management, such as understanding the facts.

Since the locking device 70 has screw holes in the beam stop ribs 77 and the frame fixing ribs 80, it can be retrofitted to an existing gaming machine. Further, since the operating plate 82 is provided with the elongated guide groove 54, the positions of the lever stop 86 and the hook stop 85 can be adjusted. As a result, even if the positions of the hook 24 and the metal frame lever 59 are different for each type of gaming machine, it can be used.

If the hook stopper 85 and the lever stopper 86 fixed to the operating plate 82 of the shaft 75 are covered with a cover, it is possible to move the hook stopper 85 and the lever stopper 86 using a device such as wire. It can be prevented. Therefore, by attaching the lock device 70 of the present invention to a gaming machine equipped with a conventional locking device, the front frame 14 or the glass frame 36 can easily be stolen in the store at a late night after the store is closed or a closed day. It is extremely effective in preventing illegal acts such as opening the door to bend the nails arbitrarily and exchanging the game control board and the ROM mounted on the game control board.

In addition, the curtain board for inspecting the inside of the island at the top of the island where the game machine is installed is opened, and a hand is inserted from there, and a hand is placed behind the game machine and the movable mechanism part is directly grasped and operated. It is impossible to do so and it can be an effective crime prevention measure. Therefore, the administrator has an excellent effect that he does not need to pay attention to the power source management.

According to the lock device of the second aspect, it is possible to prevent an illegal act on the game board surface such as opening the glass frame and bending the obstacle nail when the store is closed.

According to the lock device of the third aspect, the unlocking operation can be performed as in the conventional case. According to the lock device of claim 4, the key detection signal is used to record the fact that the front frame or the glass frame has been opened during business hours in a hall computer or the like, or by sound or visible light. It can be used for hall management and crime prevention such as reporting.
